I'm using brother's drivers which are on their website. I couldn't print at all in that threat you posted. Now I can but settings of printing does not work. So i don't think it's an driver issue as duplex work properly when set in CUPS, but when I want to change any setting different from default then there is problem because changes don't happen. Eg. I have set DuplexNoTumble In Cups and I want to print some file with every page on another piece of paper so I set Duplex to none in settings of Okular or LibreOffice or any other app and no matter what I do it will still prints as if it was set to DuplexNoTumble (it's an example).
I can give you any additional info if you want, but I simply don't know what you will need to help me so just let me know.
